Microplastics (MPs), which are tiny plastic particles (size<5 mm), have permeated every corner of the environment, emerging as contaminants in aquatic and soil ecosystems. This article explores the fate and transport of MPs from water systems into soils. MPs enter aquatic environments through various sources, such as wastewater, run-off, and industrial discharges. In water bodies, their movement is influenced by factors such as size, shape, and density. Over time, these particles can sink and become embedded in sediments. Sediments, through processes like flooding and irrigation, serve as conduits, transferring MPs into terrestrial soils. Once in soils, MPs can alter soil structure, hinder nutrient cycles, and affect microbial communities. They may also act as carriers for several pollutants, exacerbating environmental contamination. Understanding these transport mechanisms is crucial for developing predictive models and mitigation strategies to address the growing problem of MP pollution in interconnected ecosystems. Improved wastewater treatment, policies to reduce plastic use, and ecosystem restoration techniques are vital for managing MP contamination in water and soil environments.
